ATo all whom t may concern: y Y

` Be it Vknown that I, CARL E. JOHNSON, a citizen of the United States,residing at St. Paul, in the county yof Ramsey and Stateof Minnesota,have invented certain new and useful Improvementsin Combined Engine andVehicle Frames, of which the, following is a specification. v

suitable engine with its framework, transe p mission, crank and gearhousings, on or in some part of the vehicle frame. This requires themanufacture, assembling and shipping, as Well as the purchasing, of twoseparate frames or bodies, that of the vehicle and that of the engine.In fact in the manufacture of the usual tractor those parts forming thevehicle and those related to the engine are often produced in differentfactories, and bear no special relation to each other.

To save this cost of time, labor and material is one of the main objectsof the present invention.

Speaking broadly the invention consists of certain units which whenassembled form both the body of the vehicle, the support for the engine,the crank case, the support for the oil reservoir, the transmissionhousing, and the gear casing. By forming these in two separate units,with the oil reservoir separate from either, I provide a device whichcan be shipped conveniently, set up at point of delivery, and in whichone part can be removed without tearing down the entire structure.

In the accompanying drawings Figure 1 is a side elevation of my housingor frame, associated parts being shown in dotted lines.

Fig. 2 is a top plan view of the frame, certain associated parts beingin dotted lines.

vIn therdrawings 1 designates a flat: metal plate or framehavingdependingside flanges 2 and end flanges 2a. A boxing 3 is mountedon the frame 1, covering a central opening 4, and forms the upper partof the engine crank casing, the lower portion being formed by dependinginner flanges 2b carried by the frame 1 and curving slightly inwardly.

Within the opening inclosed .bv the lower` portions of these innerflanges 2b fits an Oil reservoir 5, providedwith lateral ribs 6 by meansof which it may besecured to the lower thickened edges of the flanges.

As shown in Fig. 4 there is thus formed a crank case for the engine,theends of the casing so formed having shaft openings 3a.

The frame 1 andboxing 8 formone unit.

A second unit is formed by a rear metal housing S which carries thetransmission devices, gearing, etc., the rear shaft and gearing housingbeing designated at Sa. Cover plates 9 and 10 are provided for thehousing 8, with gear caps 11,-12 and'l. This forms the second unit.These units when connected form also the frame or body of the tractor.

To'connect the units and allow forl bendy ing strains due to traveloveruneven ground, I form rearwardly extending lugs 7 on the frame 1 and aforwardly extending yoke on the housing 8. The joint thus formed by theregistration of the lugs and the forward ends of the yoke is illustratedin detail in Fig. 5. The lugs and yoke carry alining sleeves 15 and 16connected toV their outer walls, respectively, by partitions 17,18 and16a. The partitions 17, 18, on each side of the machine, being connectedby a bolt 19.

In the sleeves 15, 16, is a bushing 20 of less length than the combinedlength of the sleeves. A bolt 21 runs throughthe sleeves and projectstherefrom, and is secured by collars 22 and nuts 23, the collars bearingon the sleeves but not on the bushing, thereby allowing for bendingstrains due to undulating ground.

A front aXle 24 with its knuckle brackets 24 may also be considered aspart of the framework as on same is mounted midway its ends a V-bracket25 which supports the frame 1. f

The body or units l and 8 have a three point suspension, viz. theV-bracket 25 at the front and the two bearings on the rear axle. Theengine and driving, steering and other operating mechanism do not formApart o the present invention, but to show the general relation betweenthem and the parts above described I have shown in dotted lines thefollowing parts: The engine A, flywheel B, front wheelsC, rear aXleD,rear wheels E, seat support F, radiator Gr, brake pulley J, and itsshaft housing H, which is bolted to the ring plate 8". Y

It is thought that the above description with ,the Adrawings will makethe construcof said units being supported by one axle of Y the vehicleand the other by the other axle', lugs carried by one unit, a yokecarried by the other adapted to'register with the lugs, alining sleevescarried respectively by the yoke and lugs, bushings in ,said ksleeves ofless length than the sleeves, bolts passing through .the sleeves 'andbushings,`and collars on the bolts bearing on the sleeves and out ofcontact with the bushings, as and for the purpose set forth. v

In testimony whereof I aiiix m signature.
